<p>服务器用的是腾讯云，服务器系统为 <code>ubuntu</code></p>
<h2 id="编写nginx配置"><a class="header-anchor" href="#编写nginx配置"></a>编写<code>nginx</code>配置</h2>
<p>多站点部署主要在于 <code>nginx</code>的 <code>server</code>配置，本次部署的是<code>fisher.klause.cn</code>和<code>boards.klause.cn</code>两个网站。</p>
<p><code>ubuntu</code>的 <code>nginx</code>安装目录如下：</p>
<p><img src="https://klause-blog-pictures.oss-cn-shanghai.aliyuncs.com/2019-05-14-143332.jpg" alt="image-20181014180651310"></p>
<h3 id="1-nginx主配置"><a class="header-anchor" href="#1-nginx主配置"></a>1. <code>nginx</code>主配置</h3>
<p>确保<code>nginx.conf</code>中 <code>http</code>配置项中有<code>include /etc/nginx/conf.d/*.conf;</code></p>
<p>（没有的话自己加上就可以了）</p>
<blockquote>
<p><code>nginx</code>配置是顺序读取的，会使用第一条配置</p>
<pre><code class="language-c">include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
</code></pre>
</blockquote>
<h3 id="2-server多站点配置"><a class="header-anchor" href="#2-server多站点配置"></a>2. <code>server</code>多站点配置</h3>
<p>在<code>/nginx/conf.d/</code>目录下新建两个站点（<code>fisher.klause.cn</code>和<code>boards.klause.cn</code>）的配置文件，分别命名为<code>fisher.conf</code>和<code>boards.conf</code></p>
<blockquote>
<p><code>include /etc/nginx/conf.d/*.conf;</code><br>
这句话要求配置文件命名必须以<code>.conf</code>结尾</p>
</blockquote>
<p><img src="https://klause-blog-pictures.oss-cn-shanghai.aliyuncs.com/2019-05-14-143336.jpg" alt="image-20181014182241324"></p>
<ul>
<li>
<p>编写<code>fisher.conf</code>配置</p>
<pre><code class="language-c">server {
        listen  80;
        server_name www.fisher.klause.cn fisher.klause.cn;

        access_log /var/log/nginx/fisher.klause.cn;

        location /static {
                alias /home/ubuntu/web_site/fisher/app/static;
        }

        location / {
                proxy_pass http://127.0.0.1:8000;
                proxy_set_header Host $host;

                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}
</code></pre>
</li>
<li>
<p>编写<code>boards.conf</code>配置</p>
<pre><code class="language-c">server {
        listen  80;
        server_name www.boards.klause.cn boards.klause.cn;

        access_log /var/log/nginx/boards.klause.cn;

        location /static {
                alias /home/ubuntu/web_site/djangoboards/static;
        }

        location / {
				proxy_pass http://127.0.0.1:9000;
                # proxy_pass http://unix:/tmp/boards.klause.cn.socket;
                proxy_set_header Host $host;

                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}
</code></pre>
</li>
</ul>
<p>很容易看出两个配置项的主要区别在于：</p>
<ul>
<li>
<p><code>server_name</code>：监听的域名</p>
</li>
<li>
<p><code>access_log</code>：不同站点记录日志的位置不一样</p>
</li>
<li>
<p><code>location /static</code>：不同站点的静态文件存放的位置不一样</p>
</li>
<li>
<p><code>proxy_pass</code>：<strong>反向代理</strong></p>
<blockquote>
<p>这里是最重要的</p>
<p>虽然反向代理的地址都是<code>127.0.0.1</code>，但是代理的端口号不同<br>
<code>fisher.klause.cn</code>对应的反向代理端口号为<code>8000</code>，访问<code>fisher.klause.cn</code>的用户会被<code>nginx</code>转到<code>http://127.0.0.1:8000</code>，<code>http://127.0.0.1:8000</code>由 <code>gunicorn</code>监控，对应启动的是 <code>flask</code>应用，也就是我们的鱼书网站。<br>
<code>boards.klause.cn</code>对应的反向代理端口号为<code>9000</code>，访问<code>boards.klause.cn</code>的用户会被<code>nginx</code>转到<code>http://127.0.0.1:9000</code>，<code>http://127.0.0.1:9000</code>由 <code>gunicorn</code>监控，对应启动的是<code>django</code>应用，也就是我们的论坛网站</p>

<h2 id="启动-gunicorn"><a class="header-anchor" href="#启动-gunicorn"></a>启动 <code>gunicorn</code></h2>
<p>使用 <code>gunicorn</code>分别启动 <code>flask</code>和 <code>django</code>应用</p>
<p>启动 <code>gunicorn</code>有两种方式：命令行启动、配置文件启动</p>
<h3 id="1-使用命令行启动"><a class="header-anchor" href="#1-使用命令行启动"></a>1. 使用命令行启动</h3>
<ul>
<li>
<p>启动 <code>flask</code></p>
<pre><code>gunicorn --bind 127.0.0.1:8000 fisher:app
</code></pre>
<p>参数解释：</p>
<ul>
<li><code>--bind</code>：绑定地址、端口</li>
<li><code>fisher:app</code>：<code>fisher</code>为项目名称，<code>app</code>为核心对象</li>
</ul>
</li>
<li>
<p>启动 <code>django</code></p>
<pre><code>gunicorn --bind 127.0.0.1:9000 djangoboards.wsgi:application
</code></pre>
<p>参数解释：</p>
<ul>
<li><code>--bind</code>：绑定地址、端口</li>
<li><code>djangoboards.wsgi:application</code>：``djangoboards<code>为项目名称，使用 </code>django<code>的 </code>wsgi`启动</li>
</ul>
</li>
</ul>
<p><strong>启动时分别绑定不同的端口，端口必须与<code>server</code>配置项中的配置一致。</strong></p>
<h3 id="2-配置文件启动"><a class="header-anchor" href="#2-配置文件启动"></a>2. 配置文件启动</h3>
<p>在<code>flask</code>和 <code>django</code>项目根目录分别建立<code>gunicorn</code>的配置文件<code>gunicorn.py</code></p>
<ul>
<li>
<p>编辑<code>fisher.klause.cn</code>站点的<code>gunicorn</code>配置文件如下：</p>
<pre><code>bind = &quot;127.0.0.1:8000&quot;
workers = 2

timeout = 30
</code></pre>
<p>启动<code>flask</code>应用对应的虚拟环境 <code>fisher</code>，切换到 <code>flask</code>应用项目根目录，然后启动 <code>gunicorn</code></p>
<pre><code>gunicorn -c gunicorn.py fisher:app
</code></pre>

完美启动！</p>
</li>
<li>
<p>编辑<code>boards.klause.cn</code>站点的<code>gunicorn</code>配置文件如下：</p>
<pre><code>bind = &quot;127.0.0.1:9000&quot;
workers = 2
    
timeout = 30
</code></pre>
<p>启动<code>django</code>应用对应的虚拟环境 <code>djangoboards</code>，切换到 <code>django</code>应用项目根目录，然后启动 <code>gunicorn</code></p>
<pre><code>gunicorn -c gunicorn.py djangoboards.wsgi:application
</code></pre>
<p>参数解释：<code>-c</code> 表示使用配置文件启动，<code>gunicorn.py</code>为<code>gunicorn</code>配置文件的文件名<img src="https://klause-blog-pictures.oss-cn-shanghai.aliyuncs.com/2019-05-14-143341.jpg" alt="image-20181014191436993">完美启动！</p>
</li>
</ul>

<p>本例使用到的 <code>gunicorn</code>配置文件都是最简单的，也有复杂的配置文件，例如：</p>
<blockquote>
<pre><code># gunicorn.py
import logging
import logging.handlers
from logging.handlers import WatchedFileHandler
import os
import multiprocessing
bind = '127.0.0.1:8000'      #绑定ip和端口号
backlog = 512                #监听队列
chdir = '/home/test/server/bin'  #gunicorn要切换到的目的工作目录
timeout = 30      #超时
worker_class = 'gevent' #使用gevent模式，还可以使用sync 模式，默认的是sync模式

workers = multiprocessing.cpu_count() * 2 + 1    #进程数
threads = 2 #指定每个进程开启的线程数
loglevel = 'info' #日志级别，这个日志级别指的是错误日志的级别，而访问日志的级别无法设置
access_log_format = '%(t)s %(p)s %(h)s &quot;%(r)s&quot; %(s)s %(L)s %(b)s %(f)s&quot; &quot;%(a)s&quot;'    #设置gunicorn访问日志格式，错误日志无法设置

&quot;&quot;&quot;
其每个选项的含义如下：
h          remote address
l          '-'
u          currently '-', may be user name in future releases
t          date of the request
r          status line (e.g. ``GET / HTTP/1.1``)
s          status
b          response length or '-'
f          referer
a          user agent
T          request time in seconds
D          request time in microseconds
L          request time in decimal seconds
p          process ID
&quot;&quot;&quot;
accesslog = &quot;/home/test/server/log/gunicorn_access.log&quot;      #访问日志文件
errorlog = &quot;/home/test/server/log/gunicorn_error.log&quot;        #错误日志文件
</code></pre>

<h2 id="重启-nginx"><a class="header-anchor" href="#重启-nginx"></a>重启 <code>nginx</code></h2>
<pre><code>重启方式1：
sudo /etc/init.d/nginx restart
-------------------------------------------------------
[ ok ] Restarting nginx (via systemctl): nginx.service.

重启方式2：
sudo service nginx restart
# 该种方式输入后不会显示结果，需要去浏览器测试
</code></pre>
<h2 id="unix套接字"><a class="header-anchor" href="#unix套接字"></a><code>unix</code>套接字</h2>
<p>使用<code>unix</code>套接字可以避免端口冲突，我们看到<code>boards.conf</code>中有一句被注释的：</p>
<pre><code># proxy_pass http://unix:/tmp/boards.klause.cn.socket;
</code></pre>
<p>此处反向代理指向的是 <code>unix</code>套接字，如果使用 <code>unix</code>套接字的话，接下来启动 <code>gunicorn</code> 的时候也要监听 <code>unix</code>套接字才能使之工作，启动命令也很简单：</p>
<pre><code>gunicorn --bind unix:/tmp/boards.klause.cn.socket djangoboards.wsgi:application
</code></pre>
<p>重启 <code>nginx</code>之后也能完美工作！</p>
<p>其实套接字没什么特别的地方只是把<code>127.0.0.1:8000</code>换成了<code>unix:/tmp/boards.klause.cn.socket</code>而已</p>
